It is proposed to name the Atlantic holothuria Psolidium complanatum Cherbonnier, 1969, whose denomination is already occupied by Psolidium complanatum (Semper, 1867) from the Philippines, as Psolidium bathygalego nom. nov. 843 specimens of Psolidium bathygalego nom. nov., collected between 417 and 1191 m deep in the NW and W of Galicia and in the Galicia Bank, were studied. A detailed description of the external and internal anatomy of Psolidium bathygalego nom. nov. is made by studying the ossicles and the skeletal structure by means of scanning electron microscopy (SEM) as well as the introvert, calcareous ring, retractor muscles, water-vascular system, digestive system, respiratory trees, and reproductive system by means of micro-computed tomography (micro-CT). The habitat, feeding system, and geographical distribution of Psolidium bathygalego nom. nov. are also described.

建议将大西洋海参命名为Psolidium complanatum Cherbonnier, 1969，其名称已被来自菲律宾的Psolidium complanatum (Semper, 1867) 占据，命名为Psolidium Bathygalego nom。十一月843 个Psolidium Bathygalego标本对在加利西亚西北和西部以及加利西亚浅滩采集的 417 至 1191 米深处的 11 月的水进行了研究。 Psolidium Bathygalego nom 的外部和内部解剖结构的详细描述。十一月是通过扫描电子显微镜（SEM）研究小骨和骨骼结构，以及通过显微技术研究内向、钙质环、牵开肌、水血管系统、消化系统、呼吸树和生殖系统而制成的。计算机断层扫描（微型 CT）。 Psolidium Bathygalego nom 的栖息地、摄食系统和地理分布。十一月也有描述。
